The synthesis, characterization and X-raycrystalstructures of two 2-naphthyl-substituted pyrazoles - 3-(2-naphthyl) pyrazole (1) and 5-(2-naphthyl)-3-trifluoromethyl-pyrazole (3) - are reported. In addition, the isolation and structural characterization of 5-hydroxy-3-(2-naphthyl)-5-trifluoromethyl-4,5-dihydropyrazole (2), an intermediate of the synthesis of 3, is included. Two simple methods of
